Aggregation of imine-based metallo-supramolecular architectures through π–π interactions

Abstract

The design of supramolecular architectures based on isoquinoline-imine ligand systems is described. The isoquinoline affords an extended π surface and the use of this surface to obtain self-recognition and consequent π–π aggregation is investigated. The approach is effective in that each of four complexes is observed to aggregate through these interactions. Other π–π interactions can interfere with the aggregation indicating that a larger π-surface may be required to obtain complete control over the aggregation of the units.
